GPD 1815144 Nitrogen Oxide NOx Sensor Direct Fit Replacement

The GPD 1815144 is a direct-fit replacement Nitrogen Oxide (NOx) sensor engineered to meet or exceed OEM fit, form, and function. Designed for precise measurement of nitrogen oxide concentrations in the exhaust stream, this sensor delivers reliable real-time data to the engine control unit (ECU), enabling the emissions control system to optimize combustion and maintain regulatory compliance.

Key Features:

• Direct Fit Replacement — engineered as an application-specific drop-in replacement for the original sensor
• OEM-Quality Construction — built to factory specifications for lasting durability and accurate performance
• Emissions System Integration — works with SCR (Selective Catalytic Reduction) and NOx adsorber aftertreatment systems
• Durability Tested — every new GPD design undergoes durability testing prior to release
• North America Fitment — designed and validated for North American vehicles

GPD (Global Parts Distributors) has been a trusted name in aftermarket automotive parts since 1974, supplying engine management sensors, HVAC components, and heat exchange parts through a national warehouse network. The 1815144 NOx sensor is sold as a single unit and is the correct choice when replacing a failed or degraded nitrogen oxide sensor to resolve emissions-related DTCs and restore proper exhaust aftertreatment function.
